The brushes may be readily removed if desired, by retracting the pins 17 from the holes 16, and withdrawing the brushes from the pintles 2l or 22.

A suction fan 39 is mounted in a case 40 adjacent the rear ofthe hood 2, and is secured to the motor shaft 38 by which it is directly driven. The inlet of the fan 39 is connected -to a nozzle 41, mounted in the hood 2 and extending between the brushes 9 and l0.

n The mouth of the nozzle flares outwardly so that it extends the width ofthe machine, and is adapted to catch and draw'the water swept towards it bythe rotation of the brushes`9 and l0. s

i The outlet 42 from the fan 39 extends through the cover 8 and returns the water to Y the tank 6 from the nozzle 4l. VAhorizontal screen 43 is positioned in the tank 6 under the outlet 42 anda y,piece of vburlap, not shown,`is placedover the screen 43 to eliminate lsand and any "foreign yparticles 'from passing linto the tank outlet. A vertical screen 44 further .strains the water on its wayfto the outlet 45 and prevents any foreign matter that may accidentally pass the' screen 43 'from entering the tank 6.

A pipe 45 extends from the tank 6, and is bent to extend `transversely of the hood 2 abovethe brush 9. A rsecond pipe 46 lits within 'the pipe 45 and is provided with `perforations '47, which are adapted to yregister with holes 48'in the pipe 45to permit water to flow from the tank 6 onto the brush 9.'

The pipes45 and 46 provide a conduit 'that extends from' said tank' and discharges adjacentfthe brush 9. Y

'Itlwill be seen that by adjusting the holes 47, `48 withrelation to each other, as shown in Fig. v9, `varying' amounts of water may pass therethrough. f This adjustment is accomplished by a gear 49 lfixed to the pipe 46,.and a worm 50 meshin'gtherewith. The worm 50 is fixed to one en d of a shaftGO which extends rearwardly andisfjournalled on a bracket 6l rising from the base l to which it is secured by bolts .61` A handle 62 on the end'of the shaft BOprovides a hand grip to rotate the shaft GOto adjust-.the openings 47 48.

The f machine travels on front rollers 63 land back rollers 64. ,The front rollers 63 lare 'mounted on'racks 65 which racks extend through bearings 66 secured to the hood 2 vadjacent the forward end thereof.

Pini'ons 67 i A.fixed to'ia shaft 68 mesh with the racks 65. A gear 69 secured to the shaft 68, is engaged' by a worm 70, which is fixed toa shaft 71,'that extends rearwardly therefrom and is supported in the bracket 6l, and the bracket'7l. j

. "A handle 72 'on the shaft 71 pr'ovidesa hand grip to rotate the shaft 7l to adjust the rollers 63, through the worm 70, gear 69. pinions 67, and racks 65.

By raising and lowering the rollers 63 the mouth of the nozzle 41 is adjusted with relation to the floor, to suit various conditions.

A mop cylinder 73 is mounted in the hood 3. One end of the :mop .is journalled on a spring pin 74, identical in construction to 'the pins 17 already described, and the other end is coupled to a pintle 75, which is journalled in a Asuitable bearing 76. A gear 77 is secured to the pintle and meshes with an idler gear`7 8, whichin turnmeshes with a pinion 79 fixed 'to one end ofa horizontal transverse vshaft- 8O, lthe other end of which is provided with a worm 82 `that is in en- 'gagment with la suitable reducetionA lgear 82 connected to a rearward extension of the vmotor shaft 38. A housing 81 encloses the gear train v77 ,78,79; anda housing 81 encloses the shaft 80, worm82, and gear 82.

Handles 83 are pivotally mounted on the base l, and 'are'angularly adjustable on segments 84. A reel 85 is mounted on :a Icross member 86 .between 'the handles 83', and is adapted to have'theelectric cord, not shown, that is connected to the motor, wound ,there` 'A gland nut-i186 is threaded to the boss 87 and prevents waterleaking from around'the shaft 38 that drives the suction fan '39.

A flexible connection '88is"removably secured to the outlet 42 and extends through the coverS andmaybe'detached therefrom to permit the cover 8 to be removed from-the tank6." s' j A'filling'spout 89 provides means whereby the supply of water in tank 6 maybe replenished and also serves'as `a vent tov permit escape of air that may be'forced into `.the tank by the suctionfan 39. 7

I claim:
